Yes I'm faced with the same issue.
fusesmb installed, tried static and dynamic IP's
can't get list of smb-servers no result , query with smblookup or netbios ?
failed "smbclient -L <IP- of the share>"
failed create new smb-password using: "smbclient -a -U <smb-username>"
but Yes, I can mount manually , taping in the UNC-path of the smb-share
menu, go to, location, "smb://<netbios-name of server>/<share>
